FASTENING DEVICE FOR MILK-CAN COVERS Application filed July 29, 1925.Serial No. 46,833.

This invention relates to an improvement in fastening devices for' milkcan covers, and aims to provide a device of this character whichsecurely holds the cover in position and yet isreadily releasable andalso,

readily adjusted to locking position.

Another object of the invention resides in the provision of a device ofthis character which is permanently attached to the can and cover, butwhich permits the cover to be manipulated to fill and discharge the canand which also permits the escape of dangerous pressures.

A further object is to provide a fastening device of this characterwherein slack and wear are automatically taken up.

A still further object is to provide a device of this character which isof simple and durable construction, reliable and eifective in operation,not liable to get out oforder or to be broken,and easy and comparativelyinexpensive to manufacture.

Other objects and advantages reside in certain novel features of theconstruction, arrangement and combination of parts which will behereinafter more fully described and particularly pointed out-intheappended claims, reference being had to the accompanying drawing forminga part of this specification, and in which:

Figure 1 is a view in perspective showing the fastening device inposition to lock the cover to the can,

Figure 2 is a similar view showing the fastening device released,

Figure 3 is a fragmentary plan view of the device, as shown in Figure 1,and

Figure 4 is a view of the fastening device detached. 7

Referring to the drawing, the numeral 1 designates a milk can having aneck 2 provided with a flange 3 A cover 4 is prowhich is substantiallyrigid when finally shaped. The rod is inserted through the registeringopening at oneside, and has a washer 11 placed thereon to' engage theflange 5 of the cover and a washer 12 placed thereon to engage theflange 3 of th can. 1

Adjacent its upper end the rod is curved laterally as at 13, and thenformed with an open and almost a complete coil 14 which extends spiralfashion about and just beyond the adjacent portion of the rod 10. At itslower endthe rod is formed with an eye 15. A retractile coil spring 16is provided, and has one end connected as at 17 to the eye 15, and itsother end connected to a hook designated generally at 18. The hook 18comprises a shank 19 having a loop 20 connected to the spring 16 and abill 21 engageable with the other set of registering openings in theflanges.v of the can and cover. The device may be assembled with the canand cover by threading the coil'l4 of the rod 10 upwardly through oneset of openings prior to assembling the washer 11 thereon.

The washer 11 is then placed on the rod below the coil 14 and the coil14 is flattened out to permanently connect the rod to the openings.

I claim 1. A fastening device for securing covers to milk canscomprising a rod connected to the can and cover, a spring connected tothe rod, and a hook carried by the spring and engageable with the canand cover at a point spaced from the rod.

2. A fastening devlce for securing a cover to a milk can comprisingmeans for perma-- nently connecting the-can and cover while permittingthe cover to be moved away from and rotated relative to the can, anelastic element having one end connected to said means and adapted to bestretched around the neck of the can below'the cover, and means forreleasably connecting the other end of the elastic element to the canand cover at a point spaced from said first mentioned means.

A fastening device for securing covers to milk cans comprising a rodpermanently connected to the can and cover While permitting the cover tobe moved away from and rotated relative to the can, a retractile coilspring connected to the rod and adapted to be stretched around the canbelow the cover, and a hook carried by the spring and engageable withthe can and cover at a point spaced from the rod.

4. A fastening device for securing covers having apertured flanges tomilk cans having necks provided with apertured flanges and comprising arod inserted through one set of alined apertures and having an ofisetcoil at one end and an eye at its other end, a retractile coil springhaving one end'connected to the eye, and a (hook carried by the otherend of the coil spring, said hook being engageable With another set ofregistered openings when the spring is stretched around the neck of thecan.
